摘要 借助地理信息系统软件的表格操作及邻体分析功能,以海南霸王岭自然保护区的沟谷雨林为例,探讨热带雨林的取样技术。结果表明,用种-面积曲线所获得的热带雨林的最小面积往往过大,而采用重要值-面积曲线所确定的最小面积则为4000m2;无样地取样采用最近个体法,由种-点数曲线可以确定最少点数为119,而采用重要值-点数曲线,可以确定该雨林取样的最小点数为280。种-个体曲线表明,如果要获取多一倍的物种数,则所需调查的个体数应是原来的4倍。 Sampling techniques of vegetation study on tropical forest were examined with the help of table manipulation function and neighbourhood analysis function of GIS (geographic information system). An example was presented based on the survey data from a tropical ravine rain forest community at Bawangling National Nature Reserve on Hainan Island. The results indicated that the often-used species-area curve could not determine minimum area for the ravine forest, i.e. minimum area was much larger than 5 000 m2, while according to the importance value-area curve,minimal area for ravine forest was 4 000 m2. Closest individual method was adopted to study plotless sampling. Results showed that the minimal point number for species-point number curve was 119, and that for importance value-point number curve was 280. Species-individual curve indicates that the individual number needed for investigation should be multiplied fourfold, if we want to obtain doubling species number.
